No change to the pH of an aqueous solution of HF when solid KF is added in it.
pH of any solution is define as the negative logarithm of the concentration of H⁺ ion in the solution and it is represented as:
pH = -log[H⁺]
If the aqueous solution of HF we will add the solid KF then the KF solid will dissolve in the solution by dissociate into respective ions. But these ions will not affect the pH of the aqueous solution because it will not affect the concentration of H⁺ ion.
Hence, no change observe in the solution.
